如何在 php 中迭代数组对象。我的要求是保存来自 Dropbox 的以下数组的路径。有人可以帮助我吗？下面是我在尝试获取特定文件夹的文件时打印 Dropbox 给出的“var_dump($data)”时的结果。 对象看起来像:
array (size=14)

关于php - 如何在 PHP 中迭代 Dropbox 结果数组，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33953707/
出于纯粹的兴趣，我很好奇如何按顺序创建PI，而不是在过程结果之后生成数字，而是让数字在过程本身生成时显示。如果是这种情况，那么数字可以自行产生，我可以对以前看到的数字实现垃圾收集，从而创建一个无限系列。结果只是在Pi系列之后每秒生成一个数字。这是我通过互联网筛选的结果:这是流行的计算机友好算法，类机器算法:defarccot(x,unity)xpow=unity/xn=1sign=1sum=0loopdoterm=xpow/nbreakifterm==0sum+=sign*(xpow/n)xpow/=x*xn+=2sign=-signendsumenddefcalc_pi(digits

如何在buildr项目中使用Ruby？我在很多不同的项目中使用过Ruby、JRuby、Java和Clojure。我目前正在使用我的标准Ruby开发一个模拟应用程序，我想尝试使用Clojure后端(我确实喜欢功能代码)以及JRubygui和测试套件。我还可以看到在未来的不同项目中使用Scala作为后端。我想我要为我的项目尝试一下buildr(http://buildr.apache.org/)，但我注意到buildr似乎没有设置为在项目中使用JRuby代码本身!这看起来有点傻，因为该工具旨在统一通用的JVM语言并且是在ruby中构建的。除了将输出的jar包含在一个独特的、仅限ruby
我正在使用的第三方API的文档状态:"[O]urAPIonlyacceptspaddedBase64encodedstrings."什么是“填充的Base64编码字符串”以及如何在Ruby中生成它们。下面的代码是我第一次尝试创建转换为Base64的JSON格式数据。xa=Base64.encode64(a.to_json) 最佳答案 他们说的padding其实就是Base64本身的一部分。它是末尾的“=”和“==”。Base64将3个字节的数据包编码为4个编码字符。所以如果你的输入数据有长度n和n%3=1=>"=="末尾用于填充n%
我的代码目前看起来像这样numbers=[1,2,3,4,5]defpop_threepop=[]3.times{pop有没有办法在一行中完成pop_three方法中的内容？我基本上想做类似numbers.slice(0,3)的事情，但要删除切片中的数组项。嗯...嗯，我想我刚刚意识到我可以试试slice! 最佳答案 是numbers.pop(3)或者numbers.shift(3)如果你想要另一边。 关于ruby-多次弹出/移动ruby数组，我们在StackOverflow上找到一
我需要读入一个包含数字列表的文件。此代码读取文件并将其放入二维数组中。现在我需要获取数组中所有数字的平均值，但我需要将数组的内容更改为int。有什么想法可以将to_i方法放在哪里吗？ClassTerraindefinitializefile_name@input=IO.readlines(file_name)#readinfile@size=@input[0].to_i@land=[@size]x=1whilex 最佳答案 只需将数组映射为整数:@land边注如果你想得到一条线的平均值，你可以这样做:values=@input[x]
